Comment by Mark Honigsbaum

Medical historian and author of Going Viral, writing on pandemic origins and infectious disease history
As a group of experts assigned by the World Health Organization to examine Covid’s origins pointed out in a study last month, most of the peer-reviewed scientific evidence supports the theory that SARS-CoV-2 originated in a natural bat reservoir from where it passed to animals that were being sold at a market in Wuhan. Unless and until evidence emerges to suggest otherwise, that remains the most parsimonious explanation.

Statement relation comments

AI Verified The quote is directly about the same Covid-origins question as the complete statement. In context, Honigsbaum says the peer-reviewed evidence favors natural zoonotic emergence via a bat reservoir and animals sold in Wuhan, and he treats that as the default explanation absent contrary evidence, so a stance against the lab-incident claim is substantially more likely.

AI Verified The author is against the statement: he says "most of the peer-reviewed scientific evidence supports" a natural bat-reservoir origin via animals sold in Wuhan, and that this remains the "most parsimonious explanation," which explicitly favors zoonotic spillover over a lab-related incident.
